ive been on here for quite a few years, and i dont think ive ever seen an NA with stock ports run a 13s. anyone know otherwise. please inform

 

I think there were a few in the low 14's but that was with pretty much EVERYTHING done to them.

 

everything except NITROUS!!!!!

 

Stockport? Never heard of anyone getting that low. Could it happen? With enough nitrous and all other mods sure

 

i think its possible. kahren made 178 with the stock exhaust manifold and without as good as an exhaust as he plans to run. i believe 200 to the wheels in an integra runs low 13s; so say about the same weight (maybe some less) and hopefully better traction from rwd and whatever other ponies kahren can pull from the engine. i think a 13.9 is impossible not to acheive.
i'm rootin for ya!
you say youve been on here quite a few years; how many n/as with e6ks can you think of? moreso, how many stockported n/as with an e6k? i'd assume you could count them on one hand.

 

How about we make it a contest?

Since there was a lot of interested in that "free Microtech" thread a few months ago about getting an NA into the 13's, you guys want to see if it's possible?

This is what I suggest...
No slicks - drag radials are fine.
No nitrous oxide
No superchargers
No turbos
"Cold air intakes" and "ram intakes" are fine.
Intake is totally open, but no "artificial" pressurizing from a separate component.
Exhaust is totally open, but no "artificial" vacuum from a separate component.
Aftermarket EMS is okay; stock ECU's would be special mention!
I think we need to have a stock port versus street port division?
No bridge or peripheral ports.
Any Mazda OEM rotors are fine, including the RX-8 10:1 rotors.

I want an 8kRPM to 9kRPM limit on the rev limiter, but not all of you might agree.

I would rather stick with the stock intake manifold, but not all of you might agree.

Drivetrain is totally open, but it has to be a Mazda OEM part or equivalent.
This means 4.30:1 rears ends are permissable, but not a 4.88:1 retrofit rear end is legal.
Turbo II parts are permissable, including the transmission, driveshaft, rear diff, and rear axles.
Aftermarket LSD's are permissable.

Let the games begin?

That sounds like a good idea to me. Do we also separate it into vehicle generations such as 1st gen and 2nd gen? Also, what about carbs?

 

Yeah, I forgot about carbs.
I would think "stock intake manifolds" would imply "stock fuel injection", but I guess we could be explicit.

I know carb set-ups can hit 13's, so no sense making it easy.

I would like to keep all the cars to the stock fuel injection though.
Different size fuel injectors are okay.
I'm trying to eliminate kahren's funky TB to engine "manifold".

well RX-8s run mid 14s and they are 2800lbs
With a 2400lbs FC and 177hp, I think 13s are def possible

 

How about strip the hell out of a '79. Drop a S5 N/A motor with a GSL-SE transmission. Run full open exhaust and intake. New fuel management computer with a TII fuel pump. Beef up the ignition system and tune it right you could run 12's on stock ports.

 

How about we add to the list... "driveable off the track"

 

Maybe the classes should be broken down more. How's this?

1: Fastest stockport 6 port engine with a carb
a: Not limited to exhaust configuration. No outside aid such as vacuum pumps.
b: Not limited to intake configuration. No forced induction. No nitrous. No compressed air.
c: RPM limit to 9000 rpm.
d: Weight must be minimum of 2500 lbs without driver.

2: Fastest stockport 6 port engine with factory fuel injection
a: Not limited to exhaust configuration. No outside aid such as vacuum pumps.
b: Limited to any stock fuel injected factory 6 port intake manifold. No custom made manifolds. Mild manifold porting allowed. No aftermarket throttlebodies. No forced induction. No nitrous. No compressed air.
c: RPM limit to 9000 rpm
d: Weight must be at least 2500 lbs without driver.

3: Fastest stock port 6 port engine with aftermarket fuel injection.
a: Not limited to exhaust configuration. No outside aid such as vacuum pumps.
b: No intake manifold limitations. Any factory, aftermarket, or homemade manifold is allowed. No forced induction. No nitrous. No compressed air.
c: RPM limit to 9000 rpm.
d: Weight must be at least 2500 lbs without driver.

 

That's pretty much my dream RX-7 project... A worked S5na motor on a stripped FB chassis...

 

so whats this contest i hear about

free microtech? where?

 

The free Microtech contest never happened and this isn't it. This is more of an attempt at some friendly competition to find the potential of the stock 6 port engine.

 

oooooooh me tooo......... nah.... 13's n/a is quick though

 

ok soudns good, i am in!

where is my microtech !

 

now ted be nice

 

I've been reading this thread and I'll add my two cents.

I agree with whoever said "as long as its streetable" to some extent.

So you can do ANYTHING you want to your car, as long as its not the following

No bridge/pp/monster porting
No forced induction whatsoever (then this wouldn't be an na test
No mods such as Nitrous etc, this has to be a 13second car that doesn't require you to fill a bottle , remember, streetable.

When I say streetable I obviously mean that it must be easy enoughe for your mom to drive lol

 

It's far easier and less debatable if we just stick to certain "do's" and "don't's" and just leave the word "streetable" out of it. That is why I proposed it the way I did or actually just arranged what Ted said a little more.

 

I was shooting for this in my 89GXL. It was 2500lbs with stock ports and ecu that made 160rwp. I think it was low 14's with my Nitto's...I hear ecu's can make near 20rwp. I had to sell that car to pay for school.

Now once I get back from overseas with some $ I will start again. This one guy on here couple years ago did 13.9 in his 2nd gen but had a streetport. I would like the contest rules to be for 2nd gens only without streetports. This is because I know its possible for one to do 13's its just nobody puts in the effort or time. I bet I can do it when I get back but I wont be back for a couple of years ...Making to much overseas unless someone wants to help me when I come back on vacation for 2 weeks ??? Look at my sig. This is a good place to start for low 14's except I forgot to add that I had pineapple sleeves cut, shaved and J/B welded in the block. I also had S4 rotors in my S5 block damn mechanic. His shops out of business now go figure.

 

I've seen a guy take a stock motor and trans out of an 89 GTU and drop it into an old austin Healy sprite (think it was a Sprite at one time) and run 13.8 @ 102 MPH at Cecil County in MD.

That being said that car was a strip car only and probably about 1000 Lbs Lighter than a FC....

I don't think its going to happen on a FC thats able to pass a street safety inspection however

 

lag time........ post whorin

 

here is my set up
250whp street port motor (s5 rotors)
port matched manifolds
custom intake
efan
TB mod
custom header
true duals (no mufflers)
turboII tranny, drive shaft, rear end
nittos 555r
tokico 5 way with eibach
i shooting for 13's off the bottle

 

so are we gonna do this, I have a stock 86 that would be a willing candidate. Are we keeping it stock ports and stock fuel injection for FC's
